Completed in 1915, 520 West 145 St rises 5 stories over New York. Public records put it at 30 units and 25,050 square feet of floor area, on land zoned R7D. It is carried on the public rolls at a market value of $4.7M, and assessed for tax at $2.1M. In the 54 years its record reaches back, the lot has drawn 916 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 440 of its 916 records, fully 48%, fall under that one heading. Violation (250) and enforcement (95) trail well behind. 11 violations stand open against it today.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2021.

On the environmental ledger, the building posts an Energy Star score of 100, with a site energy-use intensity of 23.5 kBtu per square foot. Its operations answer for roughly 58 metric tons of CO2-equivalent a year.

Read together — 48% complaint, 54 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$4.7M of New York, written across 916 government filings.
